The Mosaic Law the Fountain of All Ethics, and the Source from Which the Greeks Drew Theirs
It is then clear also that all the other virtues, delineated in Moses, supplied the Greeks with the rudiments of the whole department of morals. I mean valour, and temperance, and wisdom, and justice, and endurance, and patience, and decorum, and self-restraint; and in addition to these, piety.
But it is clear to every one that piety, which teaches to worship and honour, is the highest and oldest cause; and the law itself exhibits justice, and teaches wisdom, by abstinence from sensible images, and by inviting to the Maker and Father of the universe. And from this sentiment, as from a fountain, all intelligence increases. “For the sacrifices of the wicked are abomination to the Lord; but the prayers of the upright are acceptable before Him,” since “righteousness is more acceptable before God than sacrifice.” Such also as the following we find in Isaiah: “To what purpose to me is the multitude of your sacrifices? Says the Lord;” and the whole section. “Break every bond of wickedness; for this is the sacrifice that is acceptable to the Lord, a contrite heart that seeks its Maker.” “Deceitful balances are abomination before God; but a just balance is acceptable to Him.” Thence Pythagoras exhorts “not to step over the balance;” and the profession of heresies is called deceitful righteousness; and “the tongue of the unjust shall be destroyed, but the mouth of the righteous drops wisdom.” “For they call the wise and prudent worthless.” But it were tedious to adduce testimonies respecting these virtues, since the whole Scripture celebrates them. Since, then, they define manliness to be knowledge of things formidable, and not formidable, and what is intermediate; and temperance to be a state of mind which by choosing and avoiding preserves the judgments of wisdom; and conjoined with manliness is patience, which is called endurance, the knowledge of what is bearable and what is unbearable; and magnanimity is the knowledge which rises superior to circumstances. With temperance also is conjoined caution, which is avoidance in accordance with reason. And observance of the commandments, which is the innoxious keeping of them, is the attainment of a secure life. And there is no endurance without manliness, nor the exercise of self-restraint without temperance. And these virtues follow one another; and with whom are the sequences of the virtues, with him is also salvation, which is the keeping of the state of well-being. Rightly, therefore, in treating of these virtues, we shall inquire into them all; for he that has one virtue gnostically, by reason of their accompanying each other, has them all. Self-restraint is that quality which does not overstep what appears in accordance with right reason. He exercises self-restraint, who curbs the impulses that are contrary to right reason, or curbs himself so as not to indulge in desires contrary to right reason. Temperance, too, is not without manliness; since from the commandments spring both wisdom, which follows God who enjoins, and that which imitates the divine character, namely righteousness; in virtue of which, in the exercise of self-restraint, we address ourselves in purity to piety and the course of conduct thence resulting, in conformity with God; being assimilated to the Lord as far as is possible for us beings mortal in nature. And this is being just and holy with wisdom; for the Divinity needs nothing and suffers nothing; whence it is not, strictly speaking, capable of self-restraint, for it is never subjected to perturbation, over which to exercise control; while our nature, being capable of perturbation, needs self-constraint, by which disciplining itself to the need of little, it endeavours to approximate in character to the divine nature. For the good man, standing as the boundary between an immortal and a mortal nature, has few needs; having wants in consequence of his body, and his birth itself, but taught by rational self-control to want few things.
What reason is there in the law's prohibiting a man from “wearing woman's clothing?” Is it not that it would have us to be manly, and not to be effeminate neither in person and actions, nor in thought and word? For it would have the man, that devotes himself to the truth, to be masculine both in acts of endurance and patience, in life, conduct, word, and discipline by night and by day; even if the necessity were to occur, of witnessing by the shedding of his blood. Again, it is said, “If any one who has newly built a house, and has not previously inhabited it; or cultivated a newly-planted vine, and not yet partaken of the fruit; or betrothed a virgin, and not yet married her;” — such the humane law orders to be relieved from military service: from military reasons in the first place, lest, bent on their desires, they turn out sluggish in war; for it is those who are untrammelled by passion that boldly encounter perils; and from motives of humanity, since, in view of the uncertainties of war, the law reckoned it not right that one should not enjoy his own labours, and another should without bestowing pains, receive what belonged to those who had laboured. The law seems also to point out manliness of soul, by enacting that he who had planted should reap the fruit, and he that built should inhabit, and he that had betrothed should marry: for it is not vain hopes which it provides for those who labour; according to the gnostic word: “For the hope of a good man dead or living does not perish,” says Wisdom; “I love them that love me; and they who seek me shall find peace,” and so forth. What then? Did not the women of the Midianites, by their beauty, seduce from wisdom into impiety, through licentiousness, the Hebrews when making war against them? For, having seduced them from a grave mode of life, and by their beauty ensnared them in wanton delights, they made them insane upon idol sacrifices and strange women; and overcome by women and by pleasure at once, they revolted from God, and revolted from the law. And the whole people was within a little of falling under the power of the enemy through female stratagem, until, when they were in peril, fear by its admonitions pulled them back. Then the survivors, valiantly undertaking the struggle for piety, got the upper hand of their foes. “The beginning, then, of wisdom is piety, and the knowledge of holy things is understanding; and to know the law is the characteristic of a good understanding.” Those, then, who suppose the law to be productive of agitating fear, are neither good at understanding the law, nor have they in reality comprehended it; for “the fear of the Lord causes life, but he who errs shall be afflicted with pangs which knowledge views not.” Accordingly, Barnabas says mystically, “May God who rules the universe vouchsafe also to you wisdom, and understanding, and science, and knowledge of His statutes, and patience. Be therefore God-taught, seeking what the Lord seeks from you, that He may find you in the day of judgment lying in wait for these things.” “Children of love and peace,” he called them gnostically.
